American Indycar Series

American open wheel racing series founded in 1988

The American Indycar Series (AIS) was an American open wheel racing series founded in 1988 by racing driver, owner, and businessperson Bill Tempero. The series utilized year-old (and older) chassis and engines from the CART series and later the Indy Racing League. CART and IRL drivers including Buddy Lazier, Jaques Lazier, Robby Unser, and Johnny Unser found early career success in the AIS.

In the mid-1980s, the once-popular Can-Am series was withering, and most teams had already defected to CART or IMSA. The last holdouts formed "CAT" (Can-Am Teams) in 1986 to take over sanctioning of the series as part of the SCCA. Two plans emerged, one keeping the Formula 5000-based cars, and others, led by Bill Tempero who favored using old CART Indy car machines. During 1986 and 1987, the CAT races were run essentially as two-class races, with the familiar full-bodied Formula 5000 cars racing alongside ex-CART Indy cars.^[1][2] CAT folded after the 1987 season.

Tempero then broke off and started his Indy car series in 1988. With an emphasis on cost savings, the cars would be powered by 5.9 L (360 in³) normally aspirated, stock block Chevrolet V-8 engines. Buddy Lazier was the first season champion. Tempero himself won one race that year, and placed third in the final season points standings.

As the series slowly began to gain competitors, the teams were allowed to run a choice of two powerplants. The aforementioned stock block Chevy, or the Buick V-6 in turbocharged or normally aspirated configuration. An equivalency formula was determined to provide for competitive balance among the different engine combinations. The chassis utilized were the March, Lola, Reynard, Eagle, and Penske from CART competition. In later years, G-Force and Dallara chassis from IRL competition saw use as well. Over the years, the AIS series had a predominantly western-based schedule, but did also have races in New York, the South, and Canada. AIS ran on mostly short ovals and road courses.

The series was reborn with new management in 2001–2002. A new management team formed the United States Speedway Series (USSS), while a new AIS under different management conducted races as well. The USSS ceased racing after 2005; the AIS shut down after 2002.

1988 AIS season

The 1988 Valvoline-Machinists Union American Indycar Series^[3] was the inaugural season of the American Indycar Series. After running mixed-class races with ex-Indy car chassis alongside the full-bodied Formula 5000-based machines in the Can-Am series in 1986–1987, this represented the first full season for Bill Tempero's Indy car series. The cars were powered by stock block Chevrolet engines, ranging from 275 to 400 cubic inch displacement.^[3] The chassis were mostly used Marches and Lolas from CART competition in 1985–1986.

The season consisted of eight races beginning at Willow Springs in California. Three of the events were to be hosted as twin-race weekends, with the season finale consisting of twin races at Willow Springs. Three of the races were held on 1⁄2 mile ovals, and rest were held on road courses. Buddy Lazier won the first season championship, with six wins out of the eight contested races. Kevin Whitesides placed second in points, posting three runner-up finishes, and was declared the rookie of the year.

Bill Tempero, who battled with Lazier in the early going, finished second, 41.08 seconds behind.

Only eight cars showed up, in front of a paltry crowd of roughly 2,500 spectators. Bill Tempero won the pole position, but elected to start the race at the back of the field. Buddy Lazier suffered an oil leak after practice in his March 86C, so the car was parked. His switched cars with his father and teammate Bob, who was driving an ex-Bobby Rahal March 85C. Lazier led all 100 laps en route to his third victory of the season. Only four cars were running at the finish.^[17][18][19]

Both were attempting to qualify (unsuccessfully) for the Indy 500.^[48] In the first race, Robby Unser started on the pole position and led the first 29 laps. Buddy Lazier took the lead on lap 30, and the two drivers raced-nose-to-tail most of the way. Unser got by Lazier for the lead on lap 87, and held him off on the last by 0.3 seconds.

Robby Unser won the pole with a track record of 14.9 seconds, and led from start to finish. Buddy Lazier finished second, but not without incident. Bill Tempero broke an oil pump in his primary car on lap 22. He parked his car in the pits, then he took over the team's back-up car (started by Arlon Koops). As Tempro was exiting the pits, he nearly tangled with Lazier, sending Lazier's car into a spin. Lazier was able to recover, and worked his way back up to second place by lap 89. Bill Scott came home third. In the second race, Greg Gorden won the pole with a new track record of 14.77 seconds. Gorden led until lap 56, when Robby Unser took over the lead. On lap 98, however, Unser suffered a broken rear end. Gorden veered to avoid contact, but spun and seized the engine. Both the first place and second place cars were out, putting Buddy Lazier into the lead. Lazier cruised to the finish, nursing a damaged gearbox. Bill Tempero finished second, driving the team's back-up car once again.^[58][59] After ten rounds, Robby Unser held a commanding points lead (254 points) over Bill Scott (137) and Buddy Lazier (143). Richard Griffin (133) was the leading rookie, and Bill Tempero (128) rounded out the top five.^[60]
